SCOE Vision

To assist members in delivering a national, regional and local intermodal transportation system that is safe, resilient, economical, efficient, environmentally sound, and aesthetically and culturally sensitive.

SCOE Mission

The Committee, and/or its Subcommittees and task forces, shall...

... Monitor federal environmental laws, regulations, procedures and guidance related to air quality, cultural resources, environmental process, and natural systems and ecological communities.
... Encourage, recommend and support programs and initiatives to streamline the environmental review process and promote environmental stewardship.
... Monitor national trends and circumstances and promote research on significant environmental issues.
... Serve as a forum to disseminate and exchange information and experiences among Member Departments and various other AASHTO Committees and Subcommittees, including the sharing of best practices and other innovations.
... Promote practices that protect and enhance the quality of the environment and promote and encourage interagency cooperation and coordination in the resolution of environmental issues.


Service to AASHTO & State​ Members

  • SCOE is AASHTO’s eyes and ears – and its resource for timely, well-informed commentary and advocacy – in the ever-changing arena of environmental policy-making and regulation.
  • ​​
  • SCOE works to strengthen the skills and expertise of transportation professionals in all the states – especially in your environmental office, wherever located, whatever size – in meeting the environmental challenges of your programs.

    All AASHTO members benefit from active participation in the work of SCOE and its four subject area subcommittees:

      • Air Quality, Climate Change, and Energy
      • Natural Resou​rces
      • Communities and Cultural Concerns 
      • Environmental Process 

    Environmental Technical Assistance Program

    ​The Environmental Technical Assistance Program (ETAP) is a critical resource for state departments of transportation that provides cost-effective services and timely information to assist state DOTs with addressing environmental challenges. 

    The goal of ETAP is to supply AASHTO members with the tools and resources necessary to enhance their department's program delivery, environmental streamlining, and environmental stewardship.

    ETAP allows AASHTO staff to collaborate with the state DOTs and other topical experts to develop comments on relevant proposed federal legislation, regulations, and guidance. 

    ETAP also provides opportunities for partnership building and collaborative problem solving among state and federal transportation and environmental organizations.​

    ​​S​tate DOT Benefits


    ETAP supports national meetings for members on important environmental topics (E.g. stormwater, air quality).

    ETAP provides members of the Standing Committee on Environment the ability to participate in environmental conferences of national importance.

    ETAP supports the development of comment letters to federal agencies on proposed rules and guidance, including topics such as stormwater, wetlands, air quality, and historic resources.

    All contributing members of ETAP receive Bloomberg BNA's Transportation/Environment Alert. This weekly newsletter highlights the latest developments in the field of transportation and environmental management, compliance, and stewardship, including federal legislative and administrative actions, State DOT case studies, and AASHTO program updates.  Explore the latest issue.


    Center for Environmental Excellence
    The Center for Environmental Excellence has been developed in cooperation with the Federal Highway Administration to promote environmental stewardship and to encourage innovative ways to streamline the transportation delivery process. The Center is designed to serve as a resource for transportation professionals seeking technical assistance, training, information exchange, partnership-building opportunities, and quick and easy access to environmental tools.​  Visit the Center.  

    Climate Change Resource Center

    AASHTO's Resilient and Sustainable Transportation Systems (RSTS) Technical Assistance Program is designed to help state DOTs understand the potential effects of climate change, and the range of strategies and options for climate change mitigation and adaptation.​ Visit the Resource Center.​​




    The Center for Environmental Excellence is eager to showcase some of the remarkable ways state departments of transportation are making communities more livable and transportation systems more sustainable. On this Earth Day we encourage you to take a few minutes to watch the video and share it with a friend.
